Servo Motor Quick start
Servo motor features:
1, precision: to achieve the location, speed and torque of the closed-loop control; to overcome the stepping motor out of step problems;
2, speed: high-speed performance is good, the general rated speed can reach 2000 to 3000 rpm;
3, adaptability: anti-overload ability, can withstand three times the rated torque of the load, the instantaneous load fluctuations and the requirements of the fast start of the occasion is particularly applicable;
4, stable: low-speed operation is smooth, low-speed operation will not produce similar to stepper motor stepping operation. Suitable for high-speed response requirements of the occasion;
5, Timeliness: motor acceleration and deceleration of the dynamic corresponding time is short, usually within tens of milliseconds;
6, comfort: heat and noise significantly reduced the application of servo motor is too much. As long as there is a power source, and the accuracy of the general requirements may be related to the servo motor. Such as: machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robots, automated production lines, such as process accuracy, processing efficiency and reliability requirements of the relatively high equipment motor on the basis of universal servo drive, add some PLC and motion control function, coupled with its own network communication function, to form a separate single-axis motion controller, independent of a certain degree of motion control functions, such as: point to point positioning, can be widely used in automated production lines and other applications The
In recent years, some enterprises of the servo drive and motor products have entered the industrialization stage, but also mainly concentrated in the CNC machine tool industry, power specifications in more than 400W, not for the entire automation and control industry to form a full range of standard products. As China's manufacturing power, in addition to CNC machine tool industry, other industries on the specifications of the demand for servo motor growth year by year, to this end, foreign servo motor manufacturers have planned or have been set up wholly-owned domestic factories, the use of local resources and cheap labor , Mass production of a variety of general-purpose servo motor products.
Domestic servo motor design and production technology has been tending to improve, mainly to the standardization, serialization, large-scale direction, only a certain size in order to have high reliability and low price and competitive products. But the domestic servo motor full digital drive technology is still relatively backward, mainly limited to the lack of practical motor digital control algorithm and high reliability of the power module, which greatly limits the promotion of domestic servo motor. AC servo motor works the same as the AC induction motor. In the stator there are two phase displacement 90 ° electrical angle of the excitation winding Wf and control winding WcoWf then a constant AC voltage, the use of Wc applied to the AC voltage or phase changes, to achieve the purpose of controlling the operation of the motor. AC servo motor with stable operation, good controllability, fast response, high sensitivity and mechanical properties and adjustment characteristics of the non-linearity of the indicators (require less than 10% to 15% and less than 15% to 25%), etc.
